hummingbirds and red

I like the concept of seeing the world in more than three colors- so much we 
are missing....

I was surprised to notice quite a bit of hummingbird activity around a 
cluster of Belamcanda chinensis this past July.  Surprised, because I hadn't 
noticed it before and to my old nose Belamcanda doesn't have a strong scent. 
  I just hadn't thought of them as nectariferous.  But I have to wonder- if 
birds see in four colors what is their sense of smell like?
It may have been that I hadn't been in the right place at the right time 
(very late afternoon) to notice the hummingbirds before.  There had been 
considerable rain the week before, after a dry spell.  Does anyone know if 
nectar production is affected by rainfall?

Another note- this particular clump of Belamcanda has quite dark nectar 
guides relative to others I have (this batch of seeds came from the PBX).  I 
don't know if this affected the relative attractiveness because the other 
clumps were not blooming.
